<div class="IPBDescription">Help needed OCing I5-750 with high voltage RAM</div>Dear all
Earlier this year I did some spending and basically totally overhauled my rig to this:
Intel I5-750 2.67GHz
4GB DDR3 Kingston Hyper-X 1600 MHz (2x2GB)
ASUS P7P55-LX Mobo
Artic Cooling Freezer Pro 7 Fan and Sink
Radeon HD 5770 1GB
Xonar DX Audio Card
Windows 7 Home Premium 64bit
Already there:
Corsair VX 550W PSU
SATA 250GB Barracuda HD
At the time of installation it was such a major improvement over my old setup that I was ignorant to any shortcomings. But now it’s been a while I’m starting to dig around the net to tweak the best for my outlay. One of the reasons I went for the I5-750 was the OC potential. Unfortunately I think I’m stuck unless anyone can help.
The RAM is rated at 1.7V – 1.9V. Now according to CPU-Z the sticks of RAM are getting only 1.5V and the bandwidth is rated only at PC3-10700 (667 MHz)
But I can’t shove 1.7V or indeed anything above 1.65V into it with an Intel chip in my setup, so I hear. I therefore can’t move the BCLK above 133MHz because its tied to my RAM with big voltage demands.
So yeah I made a mistake but do I bother doing anything about it? Is it a big enough bottleneck to sell it and get different RAM to get to 1600MHz or should I just put up with stock performances?
Everything in the Bios is set to Auto and so far its been running well enough but like most people I'd like to know if I can get more..
Many thanks and Merry Christmas!

What I'm trying is a ratio of 8 rather than 10 for baseclock : system memory multiplier and nudging the value up from 133 slowly, letting the mobo deal with voltages.
OCCT for an hour gives average of 67 degrees at 150MHz BCLK and DDR-1200MHz, 1.2V Vcore. So maybe there won't be too much extra in this particular chip.
Will try 160BCLK and DDR-1280 but I don't want to bee too much over 70 degrees.
